DESCRIPTION

These new industrial current sensors extend Honeywell’s closed loop current sensing capability. They offer increased current measuring capability up to 1000Aover an extended temperature range of -40°C to +85°C and are available with different terminal options.

The sensors are closed loop devices based on the principle of the hall effect and null balance method. The output from the current sensor is the balancing current which is a perfect image of the primary current reduced by the number of secondary turns at any time. This current can be expressed as a voltage by passing it through a resistor.
